You need to have an ai tech first and foremost. Secondly you need to give em a shot and bring em in heat. Then wait 3 days and implant them and give another shot. Then about 5-7 days later you have them ai'd. This usually results in a 90-93% success rate according to my ai tech. You can just give em a shot wait 3 days and then ai them but your success rate will only be about 60%. All this according to AI tech as we discussed it prior to ai'ing this year. Semen typically cost about 25 dollars a straw for pretty good bulls and then the semen certificate can vary in price. With most associations if you do not own the bull in question and do ai you must have a semen certificate on file with the breed association before you can register the offspring. My ai tech usually charges 25 dollars per head to ai them. I have the semen shipped to him and he stores it in his semen tank. By ai'ing you can use the best genetics in the world for fairly cheap.
